Rounds

How it works

  1. 1

    Everyone fakes an expansion

    A famous acronym appears — like "What does SCUBA actually stand for?". Each player secretly writes an expansion that sounds just official enough.

  2. 2

    Spot the real one

    All the fakes are shuffled together with the true expansion. Can you tell Self-Contained Underwater Breathing Apparatus from your friends' inventions?

  3. 3

    Score for truth and trickery

    Earn 1000 points for spotting the real expansion, plus 500 for every friend who believes your fake. The reveal shows exactly who fooled whom.

Sample rounds

Acronym challenge

What does LASER actually stand for?

Truth: Light Amplification by Stimulated Emission of Radiation

The real expansion lands beside every confident fake, then the room sees who found the truth and whose made-up science fooled the most friends.

Acronym challenge

What does CAPTCHA actually stand for?

Truth: Completely Automated Public Turing test to tell Computers and Humans Apart

The longest answer on the board is somehow real. The reveal credits correct voters, exposes each fake's author, and explains the tiny Turing test.

Acronym challenge

What does WD-40 actually stand for?

Truth: Water Displacement, 40th formula

The 40 marks the successful formula after 39 failed attempts. Players score for spotting it and for every friend who backed their fake expansion.

Best for bluffers who sound official

  • Office icebreakers where sounding corporate and completely wrong is funnier than knowing the answer.
  • Family game nights with familiar acronyms from technology, brands, science, and everyday life.
  • Trivia groups that want a bluffing round where beginners can outscore experts with one convincing fake.

Why it's fun

🧠 Sounding right beats being right

You don't need to know that LASER means Light Amplification by Stimulated Emission of Radiation — you just need a fake that sounds more official than the truth.

🎭 The reveal is the best part

Every round ends by exposing who fell for whose fake — with the real expansion and the surprisingly good story behind it.
